Study to Investigate Vagus Nerve Stimulation Paired With Motor Task for Remyelination and Functional Recovery

The goal of this clinical trial is to learn if stimulating the vagus nerve in combination with a motor task in people with multiple sclerosis can improve motor function. The main questions it aims to answer are: * Is stimulating the vagus nerve safe and feasible after demyelinating episodes? * Does a paired motor task with vagus nerve stimulation improve motor function with someone who has multiple sclerosis? Researchers will compare active vagus nerve stimulation to a sham stimulation to see if the paired vagus nerve stimulation can improve motor control. Participants will: * Come in for study visits over a six month period. Study visits are three times weekly for the first month, then single follow up visits at two, three, and six months. * During study visits, participants will complete 30 minutes of the paired vagus nerve stimulation with a motor task, specifically the grooved peg test. * At various timepoints in the study, motor and disability tests will be administered to see if there are any changes in motor control for that participants. These tests include the timed 25 foot walk test, expanded disability scale, the upper extremity portion of the Fugl-Meyer Assessment, and the Multiple Sclerosis Impact Scale - 29.
